HELP MY BABY IS SICK :(

I brought a 5 week old pomeranian last friday October 11,2013. When i got the pup home he was fine running around playing just happy. Well the next day i decided to feed the pup dog food i had purchased (kibbles and bits) every since he has been throwing up a friend suggested the parvo shot and to de worm him since the breeder had not. I haven brought puriena puppy cow and similac and mixing hoping this will help someone pls help me untill i can get him to a Vet.] .gif"/>
